performing an inertial force correction for removing an inertial force component from the acquired motion information by using an inverse vector of the inertial acceleration corresponding to an inertial force; and

displaying a screen corresponding to the inertial force-corrected motion information,

wherein the inertial force correction comprises removing the inertial force component that corresponds to motion information acquired while adjacent images of the plurality of images are not changed,

wherein the performing of the inertial force correction comprises;

acquiring a biometric signal from a body part of at least one user when the user moves the electronic device, and

removing the inertial force component that corresponds to motion information acquired when the biometric signal is not acquired.

acquiring orientation information of the electronic device; and

removing the inertial force component which corresponds to motion information acquired while orientation information is not changed.

6. The method of claim 1, wherein the performing of the inertial force correction comprises removing the inertial force component which corresponds to a linear component of the motion information.

7. The method of claim 6, wherein the displaying of the screen corresponding to the inertial force-corrected motion information comprises displaying the screen in accordance with a rotation component of the motion information.

8. An electronic device comprising:

a display;
